METHOD FOR SEPARATING A GAS MIXTURE FLOW USING TEMPERATURE-CHANGE ADSORPTION, AND TEMPERATURE-CHANGE ADSORPTION PLANT

CA 03088717 2020-07-16 P18C014-CA(WO) Abstract The invention relates to a method for separating a gas mixture flow, in which use is made of a temperature-change adsorption plant (100) which has a number of adsorption units (A1, A2, A3) which are respectively operated in a first operating mode and a second operating mode, wherein the first operating mode comprises guiding the gas mixture flow (G) at least in part through an adsorption chamber of the respective adsorption unit (A1, A2, A3) and subjecting this flow to an adsorptive exchange of material with at least one adsorbent in its adsorption chamber, and the second operating mode comprises guiding a first heat transfer fluid flow (W1) at a first temperature through a heat-exchange arrangement of the respective adsorption unit (A1, A2, A3) and transferring heat from the first heat transfer fluid flow (W1) indirectly to the at least one adsorbent in its adsorption chamber. It is provided that the first operating mode comprises guiding a second heat transfer fluid flow (W2) at a second temperature through the heat-exchange arrangement of the respective adsorption unit (A1, A2, A3) and transferring heat from the at least one adsorbent in its adsorption chamber indirectly to the second heat transfer fluid flow (W2), and the adsorption units (A1, A2, A3) are respectively operated in a third operating mode which comprises guiding a third heat transfer fluid flow (W3) at a third temperature through the heat-exchange arrangement of the respective adsorption unit (A1, A2, A3) and transferring heat from the at least one adsorbent in its adsorption chamber to the third heat transfer fluid flow (W3). The invention also relates to a corresponding temperature-change adsorption plant (100).
